In 2026, green sukuk is increasingly positioned as a practical route for funding mobility and sustainable infrastructure in Saudi Arabia. A green sukuk is a Shariah-compliant instrument where proceeds are restricted to environmentally beneficial projects, and investors hold partial ownership in real assets rather than earning interest. Sources describe eligible categories that can include clean transport, renewable energy, energy efficiency, sustainable water management, and climate adaptation. This matters for large transport programs because the structure requires a tangible asset or project, Shariah supervisory review, and a clear use-of-proceeds approach that can be tracked and reported.
The market backdrop is supportive, and it is getting more standardized. S&P Global projects total sukuk issuance to reach $280 billion in 2026, and separate reporting notes global sukuk issuances increased by 12.7% year on year in 2025. In 2024, about $180 billion in sukuk was issued, according to one source, and green and sustainable sukuk are described as about 10% of the total sukuk market. On the sustainable side, Fitch Ratings reported ESG sukuk outstanding crossed $44.5 billion by early 2025, a 23% year-on-year increase. For project sponsors and investors, these figures signal expanding liquidity for structures that can be aligned with transport decarbonization goals.
Why Saudi Mobility Sponsors Are Turning to Green Sukuk
Saudi Arabia’s policy framing also pushes issuance toward sustainability-linked use cases. Sources connect Vision 2030 to renewable energy, sustainable infrastructure, and broader sustainability initiatives, and describe the Saudi Green Initiative 2025–2030 as a $187B plan to cut carbon emissions, plant 10B trees, and boost renewable energy under Vision 2030 goals. For cities, municipal sukuk are described as being in a pilot phase, with Riyadh and Jeddah exploring the model for local priorities such as public transport improvements and affordable housing, with expectations that these instruments scale from 2026 onward as frameworks mature. In parallel, the same Saudi sukuk guide notes government sukuk are issued monthly by the Ministry of Finance, are tradable on Tadawul, and typically direct funds toward infrastructure projects such as transport, housing, and utilities.
Standard-setting has also tightened what “green” means in a sukuk context, which supports investor confidence when funding large mobility assets. In April 2024, ICMA, the Islamic Development Bank, and the London Stock Exchange Group published dedicated guidance on labeling sukuk as green, social, or sustainability instruments. The guidance mirrors the ICMA Green Bond Principles while adding Shariah-specific overlays across four pillars: use of proceeds, project evaluation and selection, management of proceeds, and reporting, including annual allocation and impact reporting with independent external review recommended. In July 2025, the IsDB published an updated Sustainable Finance Framework aligned with the 2025 edition of the ICMA Green Bond Principles, reinforcing a clearer pathway for issuers tying capital to climate-positive infrastructure.
Saudi issuance momentum in the wider sustainable sukuk space adds context for Saudi green sukuk transport financing in 2026, even when proceeds are not solely mobility-specific. Arab News, citing S&P Global, reports Saudi issuers led sustainable sukuk issuance in 2025, representing over 40%, followed by the UAE and Malaysia. The same reporting notes Saudi banks issued more than $15 billion in sukuk, including nearly $12 billion in foreign-denominated offerings, to support Vision 2030 initiatives. Another source describes Saudi Awwal Bank’s USD 650 million Additional Tier 1 green sukuk, which had a Second Party Opinion from S&P Global, and notes that green notes proceeds were described as funding Vision 2030-aligned projects including renewable energy and sustainable infrastructure. Together, these patterns show how transport megaproject sponsors can draw on expanding sukuk demand while meeting tighter labeling and reporting expectations.
